PAPER-BOX MACHINE.

I SPECIFICATION forming part of Letters Patent No. 364,161, dated May 31 1887.

Application filed April 12, 1886.

To all whom it may concern:

Be it known that I, GEORGE H. Gust-(MAN,-

which is to form one end of the box, is pasted,

and thereafter automatically fed forward into position above the box-rest to have its pasted 1 side brought into contact with the body of the box, supported by the said box-rest, all in continuous operation.

In paper-boxhiachines as heretofore constructed and known to me each end blank had one of its sides pasted at the edges, and

the blank so pasted was removed by the operator and placed upon the box-body held by the box-rest, the end blank being thereafter pressed firmly upon the box-body bya presserplate, which was forced down upon the said end blank by the operator working a treadle, said treadle through suitable mechanism imparting a downward movement to saidpresserplate.

My invention consists, essentially, in the combination,with a pasting mechanism, a boxrest, and a presser-plate, of an automaticallyoperating feeder, whereby the pasted end blank is transferred from the pile of blanks 5 into position to be forced closely in contact with the end of the box-body. I

As the end blank is being fed into position under the presser-plate it travels in a guideway, which insures the correct presentation 0 of the end blank to thB'bOX-bOdY, thereby enabling the end blank to be applied uniformly. Other features of my invention will be described, and will be specified in the claims.

Figure 1 is a front elevation of a machine 5 by which to practice my invention; Fig. 2, a side elevation of Fig. 1; Fig. 3, an underside View of part of the cross-head and its attached parts, the paste-pan and angle i'rons being omitted; Fig. 4, an enlarged detail showing the pastors and plate, to which they are se- Serial No. 198,530. (No model.)

I cured, as removed from the paste-pan; Fig. 5, a top view of the machine; Fig. 6,a transverse section 0f;Fig. 5 on line a m," Fig.7, a longitudinal section of Fig. 5 on line 3 y; Fig. 8, an enlarged detail of one of the pastersdetached; Fig. 9, a sectional detail tomore plainly show the form of the presser-plate,the section being taken on line w' a, Fig. 7, and Fig. 3 a perspective view ofa box-body and pasted end blank.

The frame-work of the machine, consisting of the sides A,united by therods A and girder 'A the movable cross-head A secured to the verticallysliding rods, A, extended through guides attached to the sides A, and also the girder A", as shown in Fig. 1, and secured to the foot-plate A by nuts A, are and may be of any ordinary construction, such as found in paper-box machines.

The movable cross-head A has secured to its under side, by bolts a a, (see Figs. 1, 5, and 6,) arms or plates a which extend rearward therefrom horizontally. These arms near the center of their length have attached to them by screws angle-ironsa, (see Fig. 2,) which by screws 61 are attached to a pan, a containing paste, the said pan being thus suspended below the said arms and extending across the space between them.

Above the top of the pan (1? the arms a have adj ustably secured to them the base portions a (see Fig. 6) of the blank-guides a, the said base portions also supporting tracks a upon which rests the lowest end blank as it is being fed forward by the feeder, as will be described.

Within the pan a, and normally resting on its bottom, is a plate, b, (see Figs.'4= and 6,) to which are secured plates b b, said plates supporting rods b upon which are placed pasters If, the plates 1) being adjustable by screws 63in slots thereof, so that the pastors may be moved to be adapted to operate on end blanks of different sizes, the pasters on the rodssupported by the plate b being extended the 95 length of the plate b. The plateb is herein shown as having'arms" 12 one at each end, which are extended up over the sides of the pan o as best shown in Fig. 6, wherein they are secured by screws 64 to uprights b, one at 100,

each side of the machine, which are held by screws in brackets b, attached to an upright, If, supported by the girder A To the under side of the arms a", and at the rear of the machine, are two depending studs, 0, (see Figs. 2 and 5,) which, as herein shown, converge and form bearings for an arbor. c, on which is pivoted an elbow-lever, c. The long arm of the lever c is connected bya pin, a, to a link, 0, (see Figs. 2, 5, and 7,) the other end of said link being joined by a pin, 0", to an ear, 0, (see Fig. 3,) depending from the under side of a plate,'c, said plate constituting the end-blank feeder of the machine. The short arm of the elbow-lever c is slotted to receive a. stud, d, of a link, d, pivoted by the stud d to the arm (1, secured to the standard b.

The cross-head A and its attached parts are herein shown as moved. downward by means of a treadle, d, having its fulcrum d on the foot-plate A, (see Fig. 1,) the other end of said treadle beingjoined by link (1'' to the ear d at the lower side of the girder A the upper end of said link being pivoted to said ear. The cross-head A and its attached parts are normally held elevated, as in Figs. 1 and 2, by springs e, which encircle the rods A at their lower extremities, and are each maintained in its adjusted position by a setscrew, e

Depression of the treadle causes the descent of the cross-head A", and at the same time the feeder c is drawn or moved backward in guideways e, made in the arms a*, (see dotted lines, Fig. 5,) movement being imparted to said feeder through the elbowlev'er c and secondary mechanism above described. The pasters b being stationary, the cross-head A in its downward movement lowers the paste- -pan a away from the plate I) and the pasters I), supported by it, leaving the said pasters uncovered by the paste in the pan, and at the same time brings the undermost end blank of the pile of end blanks between the guides or in contactwith said pastels, thereby wetting three edges of said blank with paste, said Wetted blank being shown in Fig. 3', the mechanism for reciprocating the feeder being so arrangedas to move itto uncover the pasters, and thereby permit the lowermost end blank to be brought against them to be pasted, as described. When the lowermost end blank has been moistened with paste, the pressure is removed from the treadle, and the springs 0 effect the elevation of the cross-head A and. with it the pastepan, the paste contained therein again covering the pasters b. Bent fingers ff, secured (see Figs. 5 and 6) to the upper side of the cross-head A and arms a, actas additional guides for the end blanks, the fingers f being adj ustably secured to the arms a. The fingers f are of suflicient .distance above the track a to permit the passage beneath them of a single end blank acted upon by the feeder.

As the cross-head A and its attached parts are restored to their normal positions by the springs 0 the feeder c is moved forward, pushing the bottom blank before it upon the tracks a and beneath the fingers f. As the end blank referred to is pushed forward by the feeder, it entersinto and is fed forward in a groove, f (see Figs. 1 aud.9,) in the guide-rails f, said rails being hinged at f to plates f, adjustably secured to the cross-head A. (See Fig. 3.)

Between the rails f z and secured to the crosshead A is a presser-plate, f to the front face of which is fastened a preferably metal strip, f and springs f, to limit the forward movement of the end blank.

Below and in line with the presser-plate f is a box-rest, 9, supported upon the standard b, said box-rest having along its sides spring-arms 9, (see Figs. 1 and 2,) by which the box-body g (see Fig. 3) is clamped to and held in position on the said box-rest to receive the blank, which will form one end of the box when completed, the sides and bottom of the'boX-body being first bent or turned, as shown in Fig. 3", so that the said bent portions will rest upon the upper face of the boxrest.

With the pasted end blank supported by the rails f above'the box-rest,.the operator places a box-body upon said box-rest and applies pressure to the treadle, thus bringing the pasted side of the end blank in contact with the bent portions of the box-body on the boxrest, the pressure upon the treadle being sufficient to cause the end blank to firmly adhere to the said bent portions, to thus form an end for the box.

The spring-arms slide over the box body and serve to clamp it firmly to the box-rest, and the railsf being hinged are permitted to pass by the sides of the box-rest in the downward movement of the cross-head A, aspring, 9, (see Fig. 3,) restoring said rails to their normal position in the upward movement of the head A and the end blank being a trifle smaller than the end of the box-body to which it is pasted, the said hinged rails will in no way interfere with the end of the box in said upward movement; but instead of being hinged the rails may be integral with the blocksf and the blocks themselves slide backward and forward. Thus it will be noticed that while one end blank is being pressed upon a boxbody to form an end, a second end blank is being pasted, and on the upward movement of the head A"- said pasted end blank is automatically fed forward into position to form the other end of the box.

Referring to Fig. 9, it will be seen that the presser-plate, instead of being preferably flat, is of greater thickness nearest the edges, asat 3, in order to obtain great pressure on the sides of the end blanks, only theses edges of the presser-plate whichpress upon the sides of the end blank being so thickened.

Referring to Fig. 8, it will be seen that each paster b is grooved at its top, so that as the paste is removed from the pasters during the downward movement of the head A a small quantity of paste will be retained in said groove, said groove permitting a greater quantity of paste to be brought into contact with the end blank and effecting a more even distribution of said paste. Each paster also has a slot, 71., through which the rod 1) is extended, each of said pasters by reason of said slot obtaining a slight pivotal or rocking movement, whereby inequalities in the surface of the end blank in one direction are overcome, while inequalities of said surface in a direction at right angles to the first-mentioned direction are overcome by means of a vertical movement imparted to said pasteby a yielding substance, preferably a thin rubber tube, if, placed beneath the pasters, and adapted to fit into the arched portion h at the bottom of each paster; but instead of a rubber tube each individual paster may have a spring placed beneath it.

I have herein shown a treadle as one means of operating the head A but I do not desire to limit my invention to such construction, as in many instances it will be desirable to operate the machines by power applied from a shaft, such a change in no way affecting the operation'of the machine. Furthermore, it may be desirable to make the head stationary and have the box-rest movable, such arrangement requiring but little change in the machine.
